;W[qf]C[I tried to play simple in this game, and focus on punishing endgame mistakes.
I also tried to punish the hane (bend around) after my 3-3 invasion twice (lower right and top left corners).
I also tried to show you that giving up some stones can be bigger than saving them, in terms of territory. We saw that a few times.]
